Privacy policy

ClassFactor, Inc. (“ClassFactor”, “we”, “us”) provides an AI-powered study platform. This policy applies to our websites, apps, and services (the “Services”).

We collect only what we need to run the Services, we never sell your personal data, and we give you control over your information.

Account data: your name, email, and authentication details when you sign up.

Study content: the material you upload (documents, slides, audio, notes) and the questions, decks, and progress generated from it.

Usage data: how you interact with the Services, such as pages viewed, features used, and device and browser information.

Payment data: billing details are processed by our payment provider, Stripe. We do not store full card numbers.

To provide and improve the Services — generating questions, scheduling reviews, and showing your progress.

To communicate with you about your account, updates, and support requests.

To keep the Services secure, detect abuse, and meet legal obligations.

We use aggregated, de-identified data to improve question quality and our models. Your private study content is not used to train third-party models without your consent.

We share data with service providers who help us operate (for example, cloud hosting, analytics, and payments) under contracts that require them to protect it.

We may disclose data if required by law, to protect our rights, or in connection with a merger or acquisition. We do not sell your personal data.

We protect your data with encryption in transit and at rest, access controls, and regular security reviews. ClassFactor maintains SOC 2 Type II and GDPR-aligned practices.

No system is perfectly secure, but we work hard to safeguard your information and will notify you of any breach as required by law.

You can access, correct, export, or delete your data at any time from your account settings, or by contacting us.

Depending on where you live, you may have additional rights under the GDPR, CCPA, or other laws. We honor these rights for all users.

We keep your data for as long as your account is active and as needed to provide the Services. When you delete your account, we delete or anonymize your personal data within a reasonable period, except where retention is legally required.

We may update this policy from time to time. If we make material changes, we will notify you through the Services or by email before they take effect.
